This product gives you an amazing pump. Even the next day you will still feel "swool". Absolutely no downsides to this product. This is a product that I will be using permanently. I just recently mixed it with the Optimum Nutrition creatine monohydrate and I was in awe with the pump I experienced. And I experience it every time I hit the gym. Not to mention I am lifting more and recovering very quickly. Try it and thank me later ;)

Very good product, you won't feel the intense tingling from this that you do with other L-arginine based vasodilators but you will be able to work out longer and harder at the gym. Mixes well with anything, I just mix with 2 ounces of water and gulp it down. Helps with recovery also.
